1. Introduction
The purpose of this manual is to describe the DXA body composition and bone mineral density
(BMD) quality assurance programs for the clinical centers participating in the MOST study. It
provides information specific to the Hologic QDR 4500A and QDR 4500W scanner operating
under DOS or Windows based software and is intended as a supplement to the appropriate
Hologic Users’ Guide.
To use this manual effectively, it is essential to have read and understood the entire Hologic
QDR 4500 User’s Manual. The study densitometry operators are required to have participated in
a Hologic QDR 4500 training session and should be familiar with all instrument features and
procedures discussed in the Hologic User’s Manual.
During the study, any questions regarding procedures that arise should be directed to:
